Wie ich auf der Seite von linuxdriverproject sehen kann, schein das M-Audio 49e midi-keyboard und Linux nicht zu funktionieren. Dem kann ich nicht zustimmen und werde hier ein kleines HowTo posten.
- Als ersten einmal die Ausgabe von lsusb -vvv:

- Nun einmal die Ausgabe von dmesg beim Einstecken des Keyboards:

- Die Konfiguration des Kernels
Ist eigentlich sehr sehr einfach. Man muss nur **Device Drivers/Sound/Advanced Linux Sound Architecture/USB Devices/USB Audio/MIDI driver **als Modul oder fest in den Kernel kompilieren.
Schon kann man mit dem Midi-Keyboard in wine und nativ arbeiten, z.B. mit rosegarden.
